handle ctrl+c or signal interupt on ros manipulator

edit

I have a python movie it interface controller node and a move it action group. Both are being launched from the same launch file.

and when ctrl + c is pressed on the launch file I have added a signal handler to move to manipulator's arm to move to the sleep position in my python moveit interface node but move it action get's killed before it receives and executes that command. what would be the best way to handle this scenario
